The data showed an unexpected rise in US retail sales in October and a pick-up in underlying inflation.
However, the outlook for US tax cuts that could stimulate economic growth was clouded after US Senate Republicans created new political obstacles by linking the repeal of a key component of Obamacare to the tax reform plans.
"The biggest factor right now shoring up gold is the weaker dollar," said Robin Bhar, head of metals research at Societe Generale.
"Also, there's speculation that tax cuts could be a long time coming, meaning the Fed will not have to be as aggressive as it might have been."
A weaker dollar makes gold cheaper for holders of other currencies, which can stimulate demand, while lower bond yields make gold more attractive by reducing the opportunity cost of owning non-yielding bullion.
Higher interest rates tend to push bond yields higher and boost the dollar.
Spot gold was up 0.4 percent at $1,286.18 an ounce at 1415 GMT after touching $1,289.09, the highest since Oct. 20. The metal has gained 0.8 percent this week.
US gold futures for December delivery were up 0.3 percent at $1,286.60.
ANZ analyst Daniel Hynes said Wednesday's inflation data could be a trigger to break gold from the $1,265 to $1,290 range in which it has traded since mid-October.
On the technical side, resistance was at the 50-day moving average around $1,292 and a Fibonacci level at $1,297.70, ScotiaMocatta analysts said.
In other precious metals, silver was up 0.8 percent at $17.14 an ounce, platinum rose 0.9 percent to $934.30 and palladium slipped by 0.5 percent to $980.75 after touching a two-week low of $974.25.
